Question

exothermic reaction associated with decrease in entropy is spontaneous at low temperature. justify using Gibbs helmholtz equation...​

Answer 1

A solution is defined as a:

A .

Homogeneous mixture of two or more substances

B .

Heterogeneous mixture of two or more substances

C .

Homogeneous mixture of liquid and solid components only

D .

Homogeneous mixture consisting of water as one of components.

A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase. 

A solution consists of a solute and a solvent. 

The solute is the substance that is dissolved in the solvent.

For example, in a saline solution, salt is the solute dissolved in water as the solvent

Answer 2

Exothermic reaction are accomplished by a decrease in entropy.

∆S = -ve

So even ∆ H is negative to make ∆ G negative according to the equation : ∆ G = ∆ H =T ∆ S

Thus -ve value of ∆ G means the reaction is spontaneous.
